SOCKET-WRENCH.

Application filed April 21, 1915 To all whom it may concern:

Be it known that I, EMILE R. MIO'ITEL, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in. Socket-VVrenches, and declare thefollowing to be a. full, clear, and exact description of the same, suchas will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings.which form a part of this specification.

This inventicn'relates to socket wrenches and an object of the inventionis a. wrench in which the socket o-rnut engaging head is pivotallymounted for universal movemen relative to the shank whereby the deviceis adaptable for use in operating on nuts in positions inaccessiblewith. an ordinary wrench.

A- further object of the invention is a wrench of the characterstated inwhich the sockets are readily interchangeable, springs being employed tohold the socket in its position relative to the handle.

A further object of the invention is a device in which the handle islongitudinally adjustable to enable the operator to manipulate nuts thatare positioned at some distance from the outside of a mechanism, as anautomobile engine mounted in a frame. By lengthening the handle thereach of the wrench is increased.

An additional object of the invention is a wrench of the characterstated that may be folded or adjusted to small compass.

With these and other objects in view the invention consists in theconstruction and the novel arrangement of parts as hereinafter morefully described and claimed and shown in the accompanying drawings inFigure 1 is an elevation of a wrench embodying my invention showing theadaptability for operation at an angle with the' longitudinal axis ofthe bolt and nut operated on. Fig. 2 is a view of the wrench when foldedshowing in detail the means employed in holding the operating or turninghandle in position. Fig. 3 is a similar view showing the other side ofthe wrench. Fig. 4 is a side elevation of the socket employed with thewrench. Fig. 5 is a face view of the socket holder.

Similar characters refer to similar parts throughout the drawing andspecification.

The wrench consists preferably of a shank 1, having a bifurcated end2'pivotally supported in which is a pivot block 3 adapted at one end toreceive the ocket 4. As shown more clearly in Figs. 2 and 5, the pivotblock or socket support 3 is also bifurcated to receive and pivotallysupport the tongue 5 of the socket 4. As shown in Fig. 4 this tongue 5has secured thereto a pin 6, the ends of which are preferably rounded asshown and projecting equidistantly each way from the tongue. Eachfurcation of the socket support 3 is channeled or grooved at 7 toreceive the ends of the pin 6 secured to the socket tongue, and to eachfurcation of the socket support 3 is secured a flat spring plate 8, theends of which are curved outwardly as indicated at 9 to enable thesocket tongue and pin to be pushed into place readily. The spring plates8 are apertured at 10 in alinement with the grooves 7 so that, when thepin is seated in the said grooves, the plates spring back into contactwith the sides of the socket support 3 and engage over the ends of thepin 6, thus retaining the socket in the support 3. By springing eitherof the plates sidewise slightly with the thumb or finger, the socket maybe readily removed from the support.

By reason of the socket being pivoted in its support and the supportpivoted to the nuts in inaccessible positions, the shank is providedwith a tubular, telescoping, extension 11. This extension is slottedupon opposite sidesas indicated at 12 in Fig. 3, and at the extreme endof the shank a pin is inserted through the shank 1, through each of theslots 12, and a collar 13 encircling the tubular member 11. These partsare made to fit rather tightly so that some little friction existsbetween the parts whereby the said extension remains in the positionplaced and may be drawn out to its fullest extent as determined by thelength of the slots or may be set in any intermediate position as may bedesired. The tubular part 11 extends beyond the end of the shank 1 andis apertured at 14, 14, as shown to re= ceive the turning handle oroperating bai- 15'. This bar is provided with an enlargement 16 at eachend to prevent its removal through the apertures 14. A retaining block17 is also provided in the upper end of the tubular extension grooved toengage the handle and held in frictional contact therewith by mean'softhe coiled spring 18 retained in the extension by means of a screw 19 inthreaded engagement with the end of the tubular extension. The handle 15has a bent end portion 20 extendingsubstantially at a right angle withthe body of the handle and of such length that, when the bent portion isdrawn through into the apertures 11 as shown in Fig. 2, the body of thehandle lies adjacent to and parallel with the shank at which time thetubular extension may be shoved down onto the shank to close the wrenchinto the smallest possible compass.

From the foregoing description it becomes evident thatthe wrench is ofsimple form and construction and comparatively inexpensive tomanufacture, that it is adaptable for use with avariety of sockets whichare interchangeable and readily positioned in the support, and that theuniversal joint connection with the shank enables the device to be usedin positions ordinarily inaccessible with wrenches of the ordinary type.

Having thus briefly described my invention and its utility, what I claimand desire to secure by Letters Patent of the United States is- 1. In awrench, a shank, a socket support pivotally connected therewith, asocket having a pin secured thereto, the support being adapted toreceive said pin providing a pivotal mounting for the socket at rightangles to the pivotal mounting of the support, and spring retainers onthe support adapted to engage said pin.

2. In a wrench, a shank having a bifurcated end, a bifurcated socketsupport havof the socket, the ends of the furcations of the supportbeing grooved to receive said pin, and a pair of spring retainers on thesupport adapted to engage the pin and yieldably hold the socket inplace.

4. A socket wrench comprising a shank having a bifurcated end, abifurcated socket support pivotally mounted in the said bifurcated end,a socket having a tongue adapted I to engage the furcations of thesupport, a

pin projecting from each side of the tongue of the socket, the ends ofthe furcations. of the support being grooved to receive the pin, and apair of flatspring plates secured to the opposite sides of the supporthaving apertures in alinement with the said groove adapted to engage thepin, said plates being curved atthe free ends and the ends of the pinbeing rounded whereby the socket may be readily attached or detachedfrom the spring.

5. A socket wrench comprising a shank, a socket having a universal jointconnection therewith, a tubular extension in telescopic relation withthe shank, said extension being slotted upon opposite sides, a collarengaging about the extension and secured to the shank by a pin passingthrough said slots, and a turning handle mounted in the extensionadapted to be folded parallel with the said extension.

In testimony whereof, I sign this specification.
